To @ZZ whom t may concern:

Be it known that l, Feen "l, LA CHAPELLE, i

:i citizen of the United States, residing at Beverly, in the county of Essex and State of ltflassachusetts, have invented certain Improvements in Lasting and Thread-Fas tening ltfachines, of which the following `dei cription, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machine for securing in lasted position, the uppers of boots and shoes, and particularly to machines for progressively lasting the uppers and securing them permanently to their innersoles by thread.

rlthe enibodinicnt of the invention selected for illustration is especially adapted .for lasting and securing the sides of shoes, the toes of which have preferably been lasted and bound with a wire. 1t is to be understood, however, that the invention is not limited to such use but may he employed at any time in the manufacture of the shoe and at any part of the shoe where it will perform a useful operation.

lt has been proposed to employ thread fasteners to secure v'the previously lasted upper in lasted position so that the lasting tacks can be removed preparatory to the welting operation. The use of metallic fastenings for holding the upper in lasted pos1- tion during the welting operation is thus avoided and hence all danger and trouble occasioned by the ne'edles striliiug such metallic fastenings are entirely obviated. A machine designed for this work is disclosed and claimed in Letters Patent of the United States No. 1,185,108 granted May SO, 1916, on my application.

An object of this invention is to provide a machine by which the loss of time occasioned by performing the lasting as a separate operation andthe expense incurred by the use of temporary lasting fastenings in addition to the fastenings required during welting and subsequent operations as well as other disadvantages above indicated can be avoided, while retaining the advantages characteristically obtained by use of the machines andA thread fasteners of the type ent, comprise a pair of loops passingthrugh the work in spaced relation, the first loop being passed inside. the second loop` and the thread drawn tight, the fastener being in this sense a loop-locked stitch.

Features of the invention consist vin an organization including lastii'ig means` and means for insertingl individual thread fasteners to hold the upper in lasted position.

A, further feature of the invention consists in a novel organization including,last-` ing means, securing means comprising means for forming individual thread fasteners to secure the upper, and means for feeding the work. Pref .rably the lasting means consists in means for iipdrawing and overdrawing a portion of the upper, and the securing means forms through the ulpper and innersole rib individual thread connected loop locked `fasteners or stitches; As shown the loopsv lie on the inside of the rib or in the channel and the connecting thread lies on the stock covering the feather of the innersole. In the construction` shown the lasting means comprises a gripper having jaws which are closed upon the upper.1 are moved upwardlyto tension the upper, and are then moved inwardly of the shoe to lay the upper in proper relation to the inner-sole rib to be secured by the thread fasteners. The thread fastener forming mechanism comprises means for passing two loops successively through the upper and innersole rib and for interlockimg` the loops and drawing on the thread to lock the fastener.` The feeding means feeds the work a distance in excess of the length of the fastener so that successiveifasteners are separate and distinct, being connected only by a strand of thread which lies on the side of the work next to the ,machine `where assists in holding the lasted upper between fasteners. As illustrated, the feeding of the work is effected by movementof the needle and this movement is such that the distance between the fasteners is equal to the length of a fastener. tance between the fasteners may be made greater or less than the length of a fastener.

nother feature of the invention consists in an organization comprising means to cause. the needle to pass through the work and withdraw, leaving a loop on the inside of the work; then to cause it to move a fastener length in a direction opposite to the feed of the work and re-enter the work to form a second loop, means for engaging the first loop with the second loop, and means to cause the needle while it is in the work to move in the direction of the feed of the work a distance in excess of the length of the fastener, to withdraw from the work while the stitch is tightened and then to return to initial position.

Fig. 7 is a cani chart showing the relation of certain cams which operate instrumentalities with which the machine is provided;

Fig. 8 is a view of the toe of a shoe showing the thread carried around the toe to enable the binding` wire to be removed.

Referring to Fig. l of the drawings, the numeral 2 indicates the column of the machine in which a head frame 4 is supported. A work rest and channel guide 6 is rigidly supported upon a bracket 8 fixed to the frame 4. Journaled in the frame 4 is the main shaft l0 to which are secured the several cam blocks l2, 14, 16 from which operative movements of the lasting and fastener forming instrumentalities are derived. The lasting means comprises a gripper 18 having jaws 20, 22 arranged to receive the upstanding margin of a shoe presented with its innersole rib or channel against the end of the rest 6. The lower jaw 20 is rigidly secured to a gripper shank or casing 24 through which extends a stem 26 connected to the movable jaw 22, the construction being such that depression of the stem 26 will cause the jaw 22 to move toward the jaw 20 Obviously, however, the disto seize the upper. The stem 26 is depressed by a closing lever 28 pivoted on a shaft 30 and having on its rear arm 3l a roll 33 which engages a suitable cam path 85 (Fig. 1) formed in the right hand face of the cam block 12 (Fig. 3.) The closing is effected yieldingly through a spring plunger 32 mounted in a sleeve 34 formed in the outer end of the closing lever 28. rllhe gripper casing 24 is pivoted at 40 to an updraw lever 42 pivoted on the shaft 30 and having on its operating arm a roll 43 engaging a cam path 44 formed in the left hand face of the cam block 16, the path being designed to cause the gripper to move upwardly after closing to tension the upper by an updraw pull. After the updraw the gripper 1s moved inwardly of the shoe to position the upper as shown in Fig. 4 preparatory to its being secured to the innersole rib. This overdraw movement of the gripper is ef fected by a lever 46 (Fig. l) pivoted at 48 and having at' its upper end a roll 49 actuated by an open cam formed in the right hand face of the cam block 14. The 'lever 46 is connected to the gripper casing 24 by a link 50 and its motion causes thegripper immediately after the updraw to move inwardly to place the upper in position to be secured. The overt raw movement is rendered yielding by a spring 52 which is tensioned by the cam and allowed to react to effect the overdraw motion of the gripper.

The fastener' forming mechanism is in mostrespects similar to that disclosed and claimed in inv prior Letters Patent referred to above. The mechanism comprises a curved eye needle 60 which is actuated to pass successive ioops of thread through the material. After the first loop a of thread has been passed through the work it is cngaged upon the opposite side of the work by a hooked thread finger (i2 which holds the loop during the retracting movement of ythe needle and which is actuated to pass the first loop of thread o, through the second loop 7) at the proper time. After the formation of the first loop the needle is retracted and given a movement laterally with respect to the needle and opposite to the direction in which the work is to he fed a distance corresponding to the length of a fastener and then 1re-enters the work to form the second loop 25. Before the needle is retracted after the formation of the second loop it is given a lateral movement in t-he direction of the feed of the work equal to the length of a fastener plus the space to be made between fasteners. After the first loop a has been passed through the second loop b the needle is retracted and a pull is exerted upon the supply end of the thread to draw the loop a int-o the work and lock the stitch. The needle now moves laterally in a direction opposite to the feed of the work a distance equal to the space between fasteners to its initial position ready to f the iii-st loop of the next fastener. ln order to clamp the end of the thread in starting and prevent its being drawn through the work the under side of the needle is provided with a. groove est (llig. il) in which the supply side of the loop lies and is allowed to slide freely. lVhenthe needle advances the short end of the thread is clamped between the needle and the worl; and all the thread for the formation of the loop is drawn from the supply side, the advancing movement of the needle being accurately gaged to position the upper side yof the loop above the end of the thread linger.

T he needle 00 is clamped inthe usual .maiiner to a needle segment 00 fulcrunied at 08 and oseillated to impart the proper movements to the needle by a bell crank lever 70., l fulcrumed on the shaft 30. the arni 70 of the bell crank has a laterally projecting stud ill upon which a lever 76 is fulcrumed. The lever 76 is connected at its lower end to the upper portion of the needle segnunit by a link 80.` The yopposite end of the lever is provided with a bore 82 and a bearing l in which is slidingly held a pin 80 which is secured to a T-shaped member 88 having a stein journaled in a bearing 90 in a head 91. With this construction, when the bell crank lever 705 71 is rocked in one direction, for instance clockwise, a1 rocking n'iovein'ent in the opposite direction or counter-clockwise .is imparted to the needle segment through the lever 70 audits link 80. The proper movements are imparted automatically to the bell crank lever 70, 71 by a cam path 92 formed in the left hand face of the cam block 12, the arm 71 of the lever carrying a roll 94 which engages the said cam, path. ln addition to passing two loops of thread successively Vthiiough the work a lateral or feeding movement is imparted to the needle between the advaneing'` movements to cause the path of the advancing movement of the needle to be shifted and the needle is also moved laterally after the second advancing movement a greater distance in the opposite direction tok effect feeding of the worlr between the fastener forn'xing operations. As shown herein, in order to impart these lateral feeding movements the needle segment is supported upon the head 91 which is slidably mounted upon parallel guide bars 101, 102 rigidly secured to the machine frame. The proper feediuovements are automatically imparted to the head 91 by a path 103 formed in the edge of the cam block 14e which is engaged' by a cani roll 104 mounted upon a stud extending upwardly and rearwardly from the head 01 2). foi1 operating the needle segment intact when a feeding movement is imparted 'to the In order to maintain the connections needle,tlle T-shaped member 88 is jotirnaled in a bearing 108 on the head 91 and the bell crank needle lever has upon its arm 70 the laterally eritending stud 'flu'hich slidably engages a bearing inthe lever 76. 'the lever To, therefore, is permitted to slide free ly upon the stud which has a sufficient length to allow the necessary lateral or feed ing movements of the needle segment to be communicated to it by the cani path 10i-l and roll 104.. i

The thread linger (S2 which ilo-operates with the needle in forming thestitch eugages the first loop of thread formed by the first passage of the needle thrmgh the worl; and holds it during ythe retraction of the needle and the formation of the second loop by the needle as it passes through the work a second time in spaced relation from the point of first passage. rlhe thread linger is then actuated to pass the first loop through the second loop and to hold both loops during the retracting' movement of the needle so that when the needle is retracted a. second time the second loop binds upon the lirst loop and prevents withdrawal of the seeond loop with the needle. The linger 02 is supported upon a finger marrying` slide 112 which is slidingly mounted upon the parallel guides 101, 102 and is actuated to impart linear movements tothe finger by a peripheral cam path 114 formed in the cam block 12. The cam path 11-l is engaged by a cam roll 11G mounted upon a rearwardly and upwardly projecting stud l`igz on the finger carrying slide 112. ils the thread fingerinoves in a linear direction it ill.: de-

sirable to raise the upper side of t ie loop l) l in order'that the thread linger shall pass between the side of the loop and the shank of theneedle. lhisisconveniently accomplished by increasing the forward throw of the needle when passing;r the second loop through rthe work, and to this end the needle 21. n is designed to impart two forward thi-o1. e of varying degree, the second thrmv being longer than the lirst as is clearly indicated on the cam chart of Fig. 7.

After both loops of thread have been passed through the work and the tiret loop of thread has been passed through the second, theneedle is given a movement in the direction of feed of the worl; greater than the length of the stitch in order to provide a space between stitches. rVlie noedle then withdraws and a pull is exerted upon the supply end of the thread to dre-.w both loops into the work and lock the stitch.
